WINDOW.

SPECIFICATION forming part of Letters Patent No. 778,565, dated December2'7, 1904.

Application filed January 21, 1904. Serial No. 189,969.

To all whom it may concern:

Be it known that we, FRANZ J. CARL, a citizen of the United States, andHERMANN G. CARL, a subject of the'Emperor of Germany, both residing inthe city of Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in WVindows, of which thefollowing is a specification.

This invention relates to the manner of hanging window-sash es indwellings and other buildings, and is an improvement upon theconstruction shown in the patent to us, No. 471,457, dated October 13,1903.

Our main object in the present improvement has been to deviseaconstruction which will permit both sashes to be swung open not only intheir lowermost position, but also in their uppermost one. 'The latteris important more especially in warm weather, when the users desire thatthe window shall be entirely open, because this result may be obtainedwith the sash elevated where they are out of danger and out of the reachof children who might break the glass.

The invention also embodies some other features of invention which arefully set forth in the description below and illustrated in theaccompanying drawings, in which Figure 1 is an elevation of a windowembodying our invention. Fig. 2 is asection of the same on line 2 2 ofFig. 1, both sashes being omitted. Fig. 3 is a section on the line 3 3of Fig. 1. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5 is apartial edge View or the window-frame, and Fig. 6 is a partial edge viewof the lower sash. Fig. 7 is a section on line '7 7 of Fig. 6. Fig. 8 isa detail horizontal section. Fig. 9 is a section on the line 9 9 of Fig.8. Figs. 10 and 11 are detail views of portions of the hinges. Fig. 12is a plan of one of the hinged plates carried by the upper sash.

In the drawings, 15 represents the windowframe, 16 the upper sash, and17 the lower sash. Both the latter are provided with counterbalancedweights, that of the upper sash being shown at 18 and that of the lowerone at 19, the cords 50 passing over pulleys 20. But one weight is usedwith either sash in order that one side of each may be free to swingwithout detaching any sash-cord. Each sash is also provided on one sidewith hinging devices, as indicated. In the case of the upper sashsockets or eyes are formed on the ends of plates 23 and 24, and aresecured, respectively, to the top rail and the meeting-rail, as seenmore particularly at Fig. 4, and the window-frame is provided with apivot 25, adapted to enter the socket of plate 23 when the sash israised to its uppermost position and with a second pivot 26 near thevertical center of the frame adapted to enter the socket of plate 24when the sash is in said position. \Vhen the upper sash is lowered toits lower position, the plate 23 sets over the pivot 21 and plate 24engages with the pivot 22, the upper sash being thus held on pivots inboth of its extreme positions, and is thus enabled to be swung open notonly when it is lowered, but when it is in its normal or properposition. The pivots 21 and 26 may have a stop 28 and be attached to thewindow-frame by wings 29. The stop-plate limits the downward movement ofthe sash, so that the meeting-rail will not interfere with the bottom ofthe window-frame when the sash is swung in its lower position. Thesehinging devices are all located, it will be noted, on the same side ofthe sash with the counterbalanee-weight 18, and also that the plates 23and 24 are slotted at one side of the pivot-openings in them, so thatthey may pass the supports 29, by which the pivots 21 and 26 arecarried. In the case of the lower sash an upper pivot is shown at 30, abottom pivot at 31, and central pivots at 32 and 33. These pivots areall secured in the window-frame by wings 34, the central pivot havingtwo of such wings and the lower sash is provided with eyes 35, adaptedto engage said pivots and attached to the sash by a strap 36. The eyehas an opening in one side, so as to permit it to pass the supports 34.The lower sash is normally in'engagement with the pivots 31 and 33 andmoves into engagement when raised with pivots 30 and 32, and it can beswung in either its lower or its upper position. 7

Both the sashes are provided upon their swlnging edges withantifriction-rollers 40,

as in our said patent, and all of the guide-slots in the window-frameare cut away, as at 41, to permit the rollers to move out of theguideslots in the frame when the sash is swung open. Both sashes must bemoved vertically a short distance when they are to be swung from theirnormal positions in order to enable them to clear the window-frame, andin order that the window maybe positioned at the right point, so thatthe rollers will move out of the slots 41, I provide in the case of eachsash movable catches 42 upon the side frame, which can be thrown intooperative position by the finger at will. These catches are adapted tointercept the passing of the parts of the hinges carried ,by the sashand prevent them from moving too far. e also prefer to provide both thesashes with wedging devices 50, adapted to contact with stationarywedging devices on the side of the window-frame. These devices preventthe sashes from rattling and force them into close contact with thesides of the grooves in which they move. The wedging devices are solocated as not to interfere with the swinging of the sashes, butopenings 52 are formed in the inner walls of the slots in whichthesashes move, so that the cams or wedges 50 may not prevent theswinging of the sashes.

\V e claim 1. The combination in a window of sliding and swinging upperand lower sashes, the sashes carrying hinge sockets or plates andstationary hinge-pivots being provided upon the frame engaging saidsockets or plates in both the upper and the lower positions of thesashes.

2. The combination in a window of sliding and swinging upper and lowersashes, the sashes carrying hinge sockets or plates, and stationaryhinge-pivots being provided upon the frame engaging said sockets orplates in both the upper and the lower positions of the sash, saidsockets and pivots being located upon the same side of the sash with thesupporting-weight thereof.

3. The combination in a window of sliding and swinging upper and lowersashes, the sashes carrying hinge sockets or plates, and stationaryhinge-pivots being provided upon the frame engaging said sockets orplates in both the upper and the lower positions of the sashes, saidsockets and pivots being located upon the same side of the sash with thesupporting-weight thereof, and upon the opposite sides of the twosashes.

4. The combination with the sliding and swinging sash and thewindowframe,of wedging devices 50 on the sash and corresponding devices50 on the frame, serving to press the sash closely against the frame.
